IMPROVEMENT lN STREET-CAR BRAKES.

Specification forming part of Letters Patent No. 127,525, dated J une 4,1872.

Specification describing a new and useful Improvement in Street-OarBrakes, invented by JOHN STEPHENSON, of the city, county, and State ofNew York.

This invention relates to brakes for cars of street and other railroads;and consists in the construction and arrangement of parts hereinafterdescribed.

In the accompanying drawing, Figure 1 is a side view of the car-wheel,giving an edge view of the car-floor with the brake attached. Fig. 2 isa section on the line as as of Fig. 1, showing a cross-section of thebrake or clog, and the method of connecting it with the brakebar. Fig. 3is a detail view, showing the wedgeform of the dovetail projection onback of clog.

Similar letters of reference indicate corresponding parts.

In street-cars the clog-bar is usually of iron, and its connection withthe clog by the various methods hitherto adopted has not beensatisfactory. Some plans fail because they are not secure, others arecomplicated, consuming much time and unnecessary material in repairs. Bymy invention I remedy these objections, simplify the construction, andfacilitate repairs.

I make the clog A as usual, except that the side opposite the wheel isof dovetail and wedge-shaped form a portion of its length, and with arecess in the clog-bar B of corresponding form, thus making amale-and-female connection, so that the clog-bar placed in conjunctionwith the clog is retained in position by its gravity while the weight ofthe clog is sustained by the rod 0, which is hinged or turns in theeye-plate D, seen in Fig. 1.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- The pendent clog A, provided with dovetail projectionon the back thereof, and constructed to support the clog-bar B, havingcorresponding recess, in the manner and for the purpose set forth.

JOHN STEPHENSON.
